VEHICLE-WHEEL Bm.

Specification of Letters Patent;

Patent-ed Jan. 26, 1909.

Application filed. May 25, 1907. Serial No` 37,'7l7.

To all whom it may concern:

Re it known that I, EDWIN COUPLAND SHAW, a citizen oi' the United States, and a resident oi' the city of Akron, in the county of. Summit, State of Ohio, have invented certain new and useful Improvements in Vehicle-Vi/'heel ltims, (Case AJ) of which the fol, lowing is a speciiication, reference being had to the drawings forming a part thereof. lo My invention relates to that class of vehicle wheel rims shown and described in my applications, Serial Numbers 375,715 and 375,716, filed of'even date herewith, and is for a modification of the general form of structure 'therein claimed. t

As stated in the above named'cases, rims oi this'character comprise generally speaking, a rim iiXed to the felly and a detachable rim capable of being easily removed from orl attached to the fixed rim and provided with means for readily engaging or disengaging a tire. The combination oi' these two means in one device is of special advantage.

.More specitieally this invention contem plates the provision of a s )lit removable rim combined with detachab e annular tire retainingr ilangcs `the rim being. capable of contraction to free it from the flanges and of expansion to cause it to clamp the flangesA and hold itself, the flanges and the tire in a unitary self-contained structure n which the tire may be inilated and vthe whole carried from place to,A place ready to be immediately substituted for a damaged tire whenever necessary. i

Means are also provided in the shape of a locking ring which may be retained in place by a keeper, for holding the two rims in engagement. 'In this moi itication an endless keeper ring is used for holding the locking ring in place.

"lhis v'invention also contemplates the use of a specially formed keypiece for spreading the ends of the detachable split llange apart and holding them in proper position. it is to be understood however that the invention is not limited to the specific forms selected for purposes of illustration but that the different parts may be freely modified sie long as their several functions are-performed relatively to each other Without altering the eil'ective combination of elements.

in the drawings, Figure-l is a transverse section through a vtelly and rim embodyin 55 my invention and showing a tire of the usua clencher type in place upon the rim, though it is to be understood that the parts may be so formed as to engage any other form of tire. The section is taken on iine l-l of Fig. 2. Fig. 2 is an elevation of a fragment of a telly and rim constructed in accordance with my invention showing a portion of the tire, the valve stem in dotted lines and the valve casing. Fig. 3 is a section of the detachable rim and foot of the tire showing the valve stem and taken on line lil-lll of Fig. 2. Fig. 4 is a central longitudinal vertical secltion of the fixed and detachable rims and the clip and key piece shown in Fig. 2..

Referring to the drawings by reference numerals, 1. is the wheel felly to which is per manently attached in any usual or suitable mann r the 'fixed rim 2.

3 is'the detachable split rim having upstanding flanges for` laterally supporting tire retaining ilanges 5. These flanges 5 arriendless annular rings shaped to engage thfiioot ofthe tire which it is desired to use, in this case shown as a clencher tire fi. The fixed rim is provided on one edge with a iiange 7 having an inclined upper face and the other edge is provided with a surface 8 inclined inthe same general direction as the iiange surface. The detachable rim is. provided with an inclined surface 9 ada ted to engage ther flange 7 and with an inclined surface 10 0pposed to the surface S but inclined in an oposite direction thereto. A locking ring 11 is inserted between the surfaces 8 and 10 and serves to wedge the two rims in iiXed engagement. This locking ring is shown in this case as' of circular cross section though it is ob. vious that other forms. may be substituted for it and is preferably transversely s lit las shown at -i1u Fig. 4. An endless 'eep'er rin 12 is used to hold this locking ring inf? we ging position, bolts 13 being assed through holes in the telly and the eeper ring, and havingnuts 14 threaded on their outer ends and'bearing against the keeper ring. Near each end of the detachable rim 3 is formed or fixed a lug 15. each lug fitting into an appropriatesocket 16 formed in the fixed riml 2. The ends of the detachable rim are inclined towards each other from the inside outward as shown at 17. A key piece 18 is used t0 fit between these inclined ends 17 and keep them spread apart, the key piece being constructed with faces of the same incline as the ends 17 thus forming a l its normalposition between the ends ofthe detachable ring bymeans ol'- a nut 21 which is screwed on to the valve stem 22 whichis of usual form. The 'upper end 'of the valve stem carries the usual-clip 23. A dust cap 24 is shown on the inner end of the valve stem. y The operation of the device is as follows: When it is desired to remove the rim and tire from the wheel, nuts 14 are unscrewed and the dust cap 24 taken o. Keeper ring 12 can then be slipped off the bolts 13 and the locking ring 11 taken away when thedetachable rim and tire can be slipped oil' from the xed rimat the side opposite from the valve stem and raised, thus lifting the valve stem from its openin in the felly. Toremove the tire from the run, the nut 21 is removed al- .lowing the key piece 18 to be slipped down the valve stem and ont of en agement'with vthe ends of 'the split rim. 'l e ends of the split rim can no'w be drawn together and overlapped so as to' materially reduce the diameter ol the rim thus permitting the retain, ing flanges 5 and the tire to be readily slip ed on" over the ilanges 4. A new tire can t en be put in place and the parts adjusted in reverse order till they are in the position shown in the drawings. The tire may be put on the detachable rim and inflated as shown in Fig.

' 3, and the key piece drawn into place by the Ilut 21 when the tire, detachable rim and key piece will be firmly held in fixed relation and carried wherever desired so that it is always possible to have an inflated tire and rim ready to apply to the wheel wheneverv needed.

Having thus .described my invention what l claim is: l.- lln lcombination in a vehicle wheel7 a iixed rim, a detachable split rim, said rim capable ol' being contracted and expanded, a

pair of annular tire retannng flanges snpn ing lianges supported by said rim and formed for engagement with the tire, the ends of said detachable rim being inclined towards ca h other outwardly and a wedge shaped key piece having similarly inclined ends adaptedl to lit between the rim ends,. said' key piece being provided with projections adapted to take under the ends of said rim and means for holding said key piece in engagement with the said ends.

3. In combination in a vehicle Wheel, a fixed rim, a split detachable rim carrying tire engaging 'means and provided in its under side with a circumferential groove and a key, piece engaging the ends of said split rim, and provided with projections fitting said groove.

4. In combination in a vehicle Wheel, a lixed rim, a split detachable rim, a tire7 means `for fastening the tire to the s lit rim, a valve stern forthe tire, 4a clip on t e end of the valve stern,` a key piece apertured to receive the valve stem, projections on the key p iece toI take under the endsof the split rim, and a nut on the valve stem for sup orting the key piece between the ends of t e split rim and means for ypreventing circumferential movement of thesplit rim.

5. A detachable rim for a vehicle wheely comprising a transversely split tire-seating member and a key iece engaging the ends of said member, said ley piece havmg an outer face ol' substantially the same transverse contour as the outer vface.` of the tire-seating member, and provided with projections to take under the ends of said member.
